AI Technical Summary
Traditional Brayton cycle cooling systems suffer from problems such as numerous cooling ports for underwater platforms, long high-pressure seawater pipelines, large main cooler size, and low reliability.
A two-stage Brayton direct contact circulation cooling system is adopted, including a circulating medium cooling loop and an intermediate cooling loop. By directly contacting the main cooler and the central cooler, the number of cooling water inlets is reduced. The direct contact heat exchange method avoids wall corrosion and leakage, and the two-stage cooling loop is set up for optimized layout.
Significantly reduces the number of cooling water inlets, improves environmental friendliness and structural safety and reliability, avoids wall corrosion and leakage, and enhances system compactness and safety.
